Hello Rizwan Khan
Yes, it should be safe to delete Azure Migration Service resources after completing the migration. However, first verify that backup services are enabled for the migrated VMs.
Resources related to the migration service:
- Replication appliances
- Temporary storage accounts created for replication
- Migration project resources in the Azure Migrate hub
Don’t forget to cleanup/delete the on-premises resources as well.
Greetings Dominique
